Box.net has now collaborated with Sony to launch their 50GB free online storage space offer for the owners of Xperia branded Android smartphones.

The company said:

We know there are more of you out who’d love some extra space in the cloud, so I’m excited to announce that, together with Sony Ericsson, we’re running a limited-time 50GB offer to all users of Xperia Android phones (OS 2.1 or later).This promotion is active worldwide, and all you need to do is download Box for Android, then log in or sign up for an account to claim your free space.

They already are running a similar offer for LG manufactured Android smartphone and Tablet PC owners.
